Abstract
Honeybee foraging  workers  were exposed orally and by contact to  the insecticides : chlorpyrifos, alpha- cypermethrin, spinosad, B.t and orange oil to evaluate the toxic effect of these insecticides under laboratory conditions. Oral toxicity tests  of the tested insecticides to honeybee foragers, indicated that the LC50 of chlorpyrifos, alpha- cypermethrin and spinosad recorded 48.0 , 47.0, 45.0 ppm, respectively.  Also it cleared that chlorpyrifos value was the height toxicity on honeybee foragers and recorded 96% mortality percentage- but on the other hand orange oil was the lower compound that recorded 25.00ppm and 50% mortality percentage on honeybee foragers at LC50 level. As for  direct contact toxicity tests,  the bees mortality was recorded as well as  the mortality lines was illustrated, data cleared that the LC50 of chlorpyrifos, alpha- cypermethrin and spinosad 25.0, 20.0, 14.0 ppm, respectively. While orange oil treatment recorded the lowest LC50 as  2.0 ppm.  In addition , as for  the mortality percentages,  chlorpyrifos recorded 50%  occupied the  most toxic insecticides on honeybee foragers while orange oil was the lowest  recording only  4% mortality percentage. Regarding to  the Initial repellence  the result indicated that all tested compounds recorded high repellent during the first and second days through the treatments.
